Deephaven AggOps
AggOp.RdAn AggOp is the return type of one of Deephaven's agg functions. It is a function that performs the
computation specified by the agg function. These are intended to be passed directly to agg_by() or agg_all_by(),
and should never be instantiated directly be user code. For more information, see the
vignette on agg functions with vignette("agg_by").
If multiple tables have the same schema and the same aggregations need to be applied to each table, saving these objects directly in a variable may be useful to avoid having to re-create them each time:
In this example, aggregations would be a vector of two AggOps that can be reused in multiple calls to agg_by().
